中耳腔压力突变可致前庭器官损伤,引起变压性眩晕,对飞行构成威胁。笔者观察豚鼠前庭器官压力损伤后的病理学改变,为变压性眩晕研究提供形态学基础。 1 材料与方法 豚鼠42只,雌雄兼用。体重300—350g。随机分成实验组28只,对照组14只。将实验组置于低压舱中以50m/s上升至5000m,停留2min,以100m/s下降至 Mutation in the middle ear cavity pressure can cause damage to the vestibular organ, causing transfiguration dizziness and posing a threat to flight. The author observed the guinea pig vestibular organ pathological changes after pressure injury, to provide morphological basis for the study of transfiguration vertigo. 1 Materials and Methods Guinea pig 42, both male and female. Weight 300-350g. Randomly divided into experimental group 28, control group 14 only. The experimental group was placed in the low-pressure cabin to 50m / s to 5000m, stay 2min, with 100m / s down to
